-CONFIG_ARM
- The ARM series is a line of low-power-consumption RISC chip designs
- licensed by ARM ltd and targeted at embedded applications.
-
-CONFIG_IDE
- If you say Y here, your kernel will be able to manage low cost mass
- storage units such as ATA/(E)IDE and ATAPI units. The most common
- cases are IDE hard drives and ATAPI CD-ROM drives.
-
- If your system is pure SCSI and doesn't use these interfaces, you
- can say N here.
-
- Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
- for mass storage units such as hard disks. It was designed by
- Western Digital and Compaq Computer in 1984. It was then named
- ST506. Quite a number of disks use the IDE interface.
-
- AT Attachment (ATA) is the superset of the IDE specifications.
- ST506 was also called ATA-1.
-
- Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
- ATA-3. It provides support for larger disks (up to 8.4GB by means of
- the LBA standard), more disks (4 instead of 2) and for other mass
- storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
- ATA-4 and provides faster (and more CPU friendly) transfer modes
- than previous PIO (Programmed processor Input/Output) from previous
- ATA/IDE standards by means of fast DMA controllers.
-
- ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
- CD-ROM drives, similar in many respects to the SCSI protocol.
-
- SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
- designed in order to prevent data corruption and disk crash by
- detecting pre hardware failure conditions (heat, access time, and
- the like...). Disks built since June 1995 may follow this standard.
- The kernel itself don't manage this; however there are quite a
- number of user programs such as smart that can query the status of
- SMART parameters disk.
-
- If you want to compile this driver as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M here and read <file:Documentation/modules.txt>. The module
- will be called ide.o.
-
- For further information, please read <file:Documentation/ide.txt>.
-
- If unsure, say Y.
-
-CONFIG_ISA
- Find out whether you have ISA slots on your motherboard. ISA is the
- name of a bus system, i.e. the way the CPU talks to the other stuff
- inside your box. Other bus systems are PCI, EISA, MicroChannel
- (MCA) or VESA. ISA is an older system, now being displaced by PCI;
- newer boards don't support it. If you have ISA, say Y, otherwise N.
-
-CONFIG_PREEMPT
- This option reduces the latency of the kernel when reacting to
- real-time or interactive events by allowing a low priority process to
- be preempted even if it is in kernel mode executing a system call.
- This allows applications to run more reliably even when the system is
- under load.
-
- Say Y here if you are building a kernel for a desktop, embedded
- or real-time system. Say N if you are unsure.
-
-CONFIG_MCA
- MicroChannel Architecture is found in some IBM PS/2 machines and
- laptops. It is a bus system similar to PCI or ISA. See
- <file:Documentation/mca.txt> (and especially the web page given
- there) before attempting to build an MCA bus kernel.
-
-CONFIG_EISA
- The Extended Industry Standard Architecture (EISA) bus was
- developed as an open alternative to the IBM MicroChannel bus.
-
- The EISA bus provided some of the features of the IBM MicroChannel
- bus while maintaining backward compatibility with cards made for
- the older ISA bus. The EISA bus saw limited use between 1988 and
- 1995 when it was made obsolete by the PCI bus.
-
- Say Y here if you are building a kernel for an EISA-based machine.
-
- Otherwise, say N.
-
-CONFIG_HOTPLUG
- Say Y here if you want to plug devices into your computer while
- the system is running, and be able to use them quickly. In many
- cases, the devices can likewise be unplugged at any time too.
-
- One well known example of this is PCMCIA- or PC-cards, credit-card
- size devices such as network cards, modems or hard drives which are
- plugged into slots found on all modern laptop computers. Another
- example, used on modern desktops as well as laptops, is USB.
-
- Enable HOTPLUG and KMOD, and build a modular kernel. Get agent
- software (at <http://linux-hotplug.sourceforge.net/>) and install it.
- Then your kernel will automatically call out to a user mode "policy
- agent" (/sbin/hotplug) to load modules and set up software needed
- to use devices as you hotplug them.
-
-CONFIG_KCORE_ELF
- If you enabled support for /proc file system then the file
- /proc/kcore will contain the kernel core image. This can be used
- in gdb:
-
- $ cd /usr/src/linux ; gdb vmlinux /proc/kcore
-
- You have two choices here: ELF and A.OUT. Selecting ELF will make
- /proc/kcore appear in ELF core format as defined by the Executable
- and Linking Format specification. Selecting A.OUT will choose the
- old "a.out" format which may be necessary for some old versions
- of binutils or on some architectures.
-
- This is especially useful if you have compiled the kernel with the
- "-g" option to preserve debugging information. It is mainly used
- for examining kernel data structures on the live kernel so if you
- don't understand what this means or are not a kernel hacker, just
- leave it at its default value ELF.
-
-CONFIG_KCORE_AOUT
- Not necessary unless you're using a very out-of-date binutils
- version. You probably want KCORE_ELF.
-
-CONFIG_BINFMT_ELF
- ELF (Executable and Linkable Format) is a format for libraries and
- executables used across different architectures and operating
- systems. Saying Y here will enable your kernel to run ELF binaries
- and enlarge it by about 13 KB. ELF support under Linux has now all
- but replaced the traditional Linux a.out formats (QMAGIC and ZMAGIC)
- because it is portable (this does *not* mean that you will be able
- to run executables from different architectures or operating systems
- however) and makes building run-time libraries very easy. Many new
- executables are distributed solely in ELF format. You definitely
- want to say Y here.
-
- Information about ELF is contained in the ELF HOWTO available from
- <http://www.linuxdoc.org/docs.html#howto>.
-
- If you find that after upgrading from Linux kernel 1.2 and saying Y
- here, you still can't run any ELF binaries (they just crash), then
- you'll have to install the newest ELF runtime libraries, including
- ld.so (check the file <file:Documentation/Changes> for location and
- latest version).
-
- If you want to compile this as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M here and read <file:Documentation/modules.txt>. The module
- will be called binfmt_elf.o. Saying M or N here is dangerous because
- some crucial programs on your system might be in ELF format.
-
-CONFIG_BINFMT_AOUT
- A.out (Assembler.OUTput) is a set of formats for libraries and
- executables used in the earliest versions of UNIX. Linux used the
- a.out formats QMAGIC and ZMAGIC until they were replaced with the
- ELF format.
-
- As more and more programs are converted to ELF, the use for a.out
- will gradually diminish. If you disable this option it will reduce
- your kernel by one page. This is not much and by itself does not
- warrant removing support. However its removal is a good idea if you
- wish to ensure that absolutely none of your programs will use this
- older executable format. If you don't know what to answer at this
- point then answer Y. If someone told you "You need a kernel with
- QMAGIC support" then you'll have to say Y here. You may answer M to
- compile a.out support as a module and later load the module when you
- want to use a program or library in a.out format. The module will be
- called binfmt_aout.o. Saying M or N here is dangerous though,
- because some crucial programs on your system might still be in A.OUT
- format.
-
-CONFIG_BINFMT_MISC
- If you say Y here, it will be possible to plug wrapper-driven binary
- formats into the kernel. You will like this especially when you use
- programs that need an interpreter to run like Java, Python or
- Emacs-Lisp. It's also useful if you often run DOS executables under
- the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from
- <http://www.linuxdoc.org/docs.html#howto>). Once you have
- registered such a binary class with the kernel, you can start one of
- those programs simply by typing in its name at a shell prompt; Linux
- will automatically feed it to the correct interpreter.
-
- You can do other nice things, too. Read the file
- <file:Documentation/binfmt_misc.txt> to learn how to use this
- feature, and <file:Documentation/java.txt> for information about how
- to include Java support.
-
- You must say Y to "/proc file system support" (CONFIG_PROC_FS) to
- use this part of the kernel.
-
- You may say M here for module support and later load the module when
- you have use for it; the module is called binfmt_misc.o. If you
- don't know what to answer at this point, say Y.
-
-CONFIG_SCSI
- If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
- any other SCSI device under Linux, say Y and make sure that you know
- the name of your SCSI host adapter (the card inside your computer
- that "speaks" the SCSI protocol, also called SCSI controller),
- because you will be asked for it.
-
- You also need to say Y here if you want support for the parallel
- port version of the 100 MB IOMEGA ZIP drive.
-
- This driver is also available as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want).
- The module will be called scsi_mod.o. If you want to compile it as
- a module, say M here and read <file:Documentation/modules.txt> and
- <file:Documentation/scsi.txt>. However, do not compile this as a
- module if your root file system (the one containing the directory /)
- is located on a SCSI device.
-
-CONFIG_NETDEVICES
- You can say N here if you don't intend to connect your Linux box to
- any other computer at all or if all your connections will be over a
- telephone line with a modem either via UUCP (UUCP is a protocol to
- forward mail and news between unix hosts over telephone lines; read
- the UUCP-HOWTO, available from
- <http://www.linuxdoc.org/docs.html#howto>) or dialing up a shell
- account or a BBS, even using term (term is a program which gives you
- almost full Internet connectivity if you have a regular dial up
- shell account on some Internet connected Unix computer. Read
- <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>).
-
- You'll have to say Y if your computer contains a network card that
- you want to use under Linux (make sure you know its name because you
- will be asked for it and read the Ethernet-HOWTO (especially if you
- plan to use more than one network card under Linux)) or if you want
- to use SLIP (Serial Line Internet Protocol is the protocol used to
- send Internet traffic over telephone lines or null modem cables) or
- CSLIP (compressed SLIP) or PPP (Point to Point Protocol, a better
- and newer replacement for SLIP) or PLIP (Parallel Line Internet
- Protocol is mainly used to create a mini network by connecting the
- parallel ports of two local machines) or AX.25/KISS (protocol for
- sending Internet traffic over amateur radio links).
-
- Make sure to read the NET-3-HOWTO. Eventually, you will have to read
- Olaf Kirch's excellent and free book "Network Administrator's
- Guide", to be found in <http://www.linuxdoc.org/docs.html#guide>. If
- unsure, say Y.
-
-CONFIG_MAGIC_SYSRQ
- If you say Y here, you will have some control over the system even
- if the system crashes for example during kernel debugging (e.g., you
- will be able to flush the buffer cache to disk, reboot the system
- immediately or dump some status information). This is accomplished
- by pressing various keys while holding SysRq (Alt+PrintScreen). It
- also works on a serial console (on PC hardware at least), if you
- send a BREAK and then within 5 seconds a command keypress. The
- keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
- unless you really know what this hack does.
-
-CONFIG_ARCH_ARCA5K
- This selects support for 'ARM26' CPUs (ARM 2 and 3)
-
-CONFIG_ARCH_A5K
- Say Y here to to support the Acorn A5000. Linux can support the
- internal IDE disk and CD-ROM interface, serial and parallel port,
- and the floppy drive. Note that on some A5000s the floppy is
- plugged into the wrong socket on the motherboard.
-
-CONFIG_ARCH_ARC
- The Acorn Archimedes was an personal computer based on an 8MHz ARM2
- processor, released in 1987. It supported 512K of RAM and 2 800K
- floppy disks. Picture and more detailed specifications at
- <http://www.computingmuseum.com/museum/archi.htm>.
-
-CONFIG_PAGESIZE_16
- Say Y here if your Archimedes or A5000 system has only 2MB of
- memory, otherwise say N. The resulting kernel will not run on a
- machine with 4MB of memory.
-
-CONFIG_FPE_NWFPE
- Say Y to include the NWFPE floating point emulator in the kernel.
- This is necessary to run most binaries. Linux does not currently
- support floating point hardware so you need to say Y here even if
- your machine has an FPA or floating point co-processor podule.
-
- It is also possible to say M to build the emulator as a module
- (nwfpe.o) or indeed to leave it out altogether. However, unless you
- know what you are doing this can easily render your machine
- unbootable. Saying Y is the safe option.
-
- You may say N here if you are going to load the Acorn FPEmulator
- early in the bootup.
-
-CONFIG_FPE_FASTFPE
- Say Y here to include the FAST floating point emulator in the kernel.
- This is an experimental much faster emulator which now also has full
- precision for the mantissa. It does not support any exceptions.
- It is very simple, and approximately 3-6 times faster than NWFPE.
-
- It should be sufficient for most programs. It may be not suitable
- for scientific calculations, but you have to check this for yourself.
- If you do not feel you need a faster FP emulation you should better
- choose NWFPE.
-
- It is also possible to say M to build the emulator as a module
- (fastfpe.o). But keep in mind that you should only load the FP
- emulator early in the bootup. You should never change from NWFPE to
- FASTFPE or vice versa in an active system!
-
-CONFIG_DEBUG_ERRORS
- This option controls verbose debugging information which can be
- printed when the kernel detects an internal error. This debugging
- information is useful to kernel hackers when tracking down problems,
- but mostly meaningless to other people. It's safe to say Y unless
- you are concerned with the code size or don't want to see these
- messages.
-
-CONFIG_NO_FRAME_POINTER
- If you say Y here, the resulting kernel will be slightly smaller and
- faster. However, when a problem occurs with the kernel, the
- information that is reported is severely limited. Most people
- should say N here.
-
-CONFIG_DEBUG_USER
- When a user program crashes due to an exception, the kernel can
- print a brief message explaining what the problem was. This is
- sometimes helpful for debugging but serves no purpose on a
- production system. Most people should say N here.
-
-CONFIG_DEBUG_INFO
- Say Y here to include source-level debugging information in the
- `vmlinux' binary image. This is handy if you want to use gdb or
- addr2line to debug the kernel. It has no impact on the in-memory
- footprint of the running kernel but it can increase the amount of
- time and disk space needed for compilation of the kernel. If in
- doubt say N.
-
-CONFIG_DEBUG_LL
- Say Y here to include definitions of printascii, printchar, printhex
- in the kernel. This is helpful if you are debugging code that
- executes before the console is initialized.
-
-CONFIG_NO_PGT_CACHE
- Normally the kernel maintains a `quicklist' of preallocated
- pagetable structures in order to increase performance. On machines
- with very few pages this may however be a loss. Say Y here to
- disable the pgtable cache.
-
-CONFIG_ARTHUR
- Say Y here to include the kernel code necessary if you want to run
- Acorn RISC OS/Arthur binaries under Linux. This code is still very
- experimental; if this sounds frightening, say N and sleep in peace.
- You can also say M here to compile this support as a module (which
- will be called arthur.o).
-
-CONFIG_CMDLINE
- On some architectures (EBSA110 and CATS), there is currently no way
- for the boot loader to pass arguments to the kernel. For these
- architectures, you should supply some command-line options at build
- time by entering them here. As a minimum, you should specify the
- memory size and the root device (e.g., mem=64M root=/dev/nfs).
-
-CONFIG_DEBUG_KERNEL
- Say Y here if you are developing drivers or trying to debug and
- identify kernel problems.
-
-CONFIG_DEBUG_SLAB
- Say Y here to have the kernel do limited verification on memory
- allocation as well as poisoning memory on free to catch use of freed
- memory.
-
-CONFIG_DEBUG_SPINLOCK
- Say Y here and build SMP to catch missing spinlock initialization
- and certain other kinds of spinlock errors commonly made. This is
- best used in conjunction with the NMI watchdog so that spinlock
- deadlocks are also debuggable.
-
-CONFIG_DEBUG_BUGVERBOSE
- Say Y here to make BUG() panics output the file name and line number
- of the BUG call as well as the EIP and oops trace. This aids
- debugging but costs about 70-100K of memory.
-
-CONFIG_ZBOOT_ROM
- Say Y here if you intend to execute your compressed kernel image (zImage)
- directly from ROM or flash. If unsure, say N.
-
-CONFIG_ZBOOT_ROM_TEXT
- The base address for zImage. Unless you have special requirements, you
- should not change this value.
-
-CONFIG_ZBOOT_ROM_BSS
- The base address of 64KiB of read/write memory, which must be available
- while the decompressor is running. Unless you have special requirements,
- you should not change this value.
